With the victory, Jones claimed the UFC interim light heavyweight championship. Saint Preux (19-8) was a late replacement for injured champion Daniel Cormier.

Saint Preux, ranked No. 6 in the light heavyweight division, did not have enough to hang with the more aggressive Jones. He kept looking for his spots, but an impatient crowd began booing late in the third round.

"Sorry guys, if you weren't satisfied by that," Jones told the crowd after the fight. "I was watching tonight instead of reacting."

After the two felt each other out to start the bout, Jones opened the second round with a mix of kicks and hand strikes. As a last-minute replacement, Saint Preux appeared to tire in the third round. Jones dominated the fourth round, scoring a takedown early and maintaining control throughout the duration of the round.

After that first round when the strikes were fairly even (15-11 Jones), Jones held a 116-47 strike advantage, including 28-4 in the fourth round.
